Clay Matthews is an absolute beast and a nightmare for any offensive lineman who dares to get in his way.

In his second year in the NFL, he made 13.5 sacks to go along with 60 tackles, two forced fumbles and an interception.

Matthews is a player that opposing offenses need to focus on the entire time he is on the field.

Advantage: Clay Matthews

Green Bay Packers NT B.J Raji Vs. Pittsburgh Steelers Center

Steelers guard Chris Kemoeatu told the media that rookie center Maurkice Pouncey wouldn't be playing in the Super Bowl due to an ankle injury he suffered in the AFC Championship Game against the New York Jets.

If Pouncey isn't able to go, Packers nose tackle B.J. Raji will be licking his chops at the chance to have another great game.

Raji Made 39 tackles and 6.5 sacks during the 2010 season and has made a sack, as well as intercepting a pass and returning it for a touchdown in the postseason.

James Harrison has become a household name this year, due to his excessive fines for helmet to helmet hits, that resulted in changes of the NFL rules.

Harrison is a seasoned veteran and brings the heat on every down. Packers Chad Clifton is decent, but he was inconsistent in his pass protection throughout the year.

Clifton will have his work cut out for him as he takes on Harrison, who made 100 tackles, five of which for a loss, 1.5 sacks, two interceptions, deflected five passes and forced six fumbles this year.

A.J. Hawk and Desmond Bishop lead the Packers in tackles, and are the primary run stoppers. Both are productive players: Hawk (111 tackles, 10 pass deflections, three interceptions) and Bishop (103 tackles, three sacks, eight pass deflections, two forced fumbles and an interception).
